N7TFP talks about how to use an antenna tuner to tune an antenna. $\begingroup$ And, an important factor to remember: the extra power coming back from a poorly matched antenna is diverted from the radio. 0 INTRODUCTION The ATR-30 is a high power antenna tuner. Other possible side benefit is now being evaluated, as it is a VERY BROAD BAND antenna in the MONOPOLE configuration, above the HF band, to high as 3 GHz!. 5 dB for an antenna with initial VSWR of 5:1). I made that mistake myself. Antenna Auto-tuner Design, Part 5: Directional Coupler Design This, my fifth post for my Automatic Antenna Tuner, deals with the design of the Directional Coupler. To match the loop to the coax cable a high power 4:1 air core balun (1000W CW) has been inserted in a waterproof container at the feeding point of the antenna. I did not replace it with RG-8/U, because I do not use it that way, and never have had any problems with it. Any short antenna can be matched with this method, such as towers with or without capacitive hat, T antennas, inverted-L antennas, random wires, and so on, as long as they are small compared to the wavelength; shorter than a quarter wavelength in any case. AN APPROACH TO ANTENNA TUNING by Lloyd Butler VK5BR Some ideas are presented on how to match the transmitter to the complex impedance of the antenna circuit and an examination is made of the tuning range needed for matching components. A good precaution to reduce RFI problems is to insert a high quality common mode choke between the transceiver and the antenna tuner. Technically speaking, all of these names, other than Transmatch, are misnomers. The loss of power in your Drake tuner is probably on the order of Tenths-of-a-percent and the overall efficiency of the system will far exceed the loss in the antenna tuner if it were not used in line with a non-resonate system. I started out with a Harris RF-601 remote coupler but that was overkill since I really only needed to have the antenna work on 40 through 15 meters. 00 : MACO 2400 Wattmeter 20-200-2000-4000 watt scales. All information, images, and documents on this website are the sole property of MFJ Enterprises, Inc. So as long as the antenna feed point SWR is somewhat low it's hardly worth the trouble. C2 — Fixed capacitors at 4 kV, in combination as needed to resonate antenna tuner at low. To support an antenna, I have no tower, and only two trees that aren't too close to a house. Page 3 ATR-30 Instruction Manual Ameritron Antenna Tuner The ANTENNA SELECTOR selects one of 3 rear panel SO-239 coaxial connectors or the wire-type wing-nut connections. 8 to 30 MHz with a single antenna. The antenna length should NOT be ¼, ½ wavelength on any frequency that you transmit as the impedance will be very high (or low) and will not transfer through the matching unit at a favorable impedance to your antenna tuner.
